黑山大小蠹(Dendroctonus ponderosae)和波缝重齿小蠹(Ips pini)危害同一株扭叶松时,前者主要危害树干的下部,而后者主要侵害已受黑山大小蠹危害林木的上部树干。对受害林木树皮表面羽化孔的调查表明:两种小蠹虫羽化孔的数目呈明显的负相关。室内段木接虫试验表明:同时接种两种小蠹虫,黑山大小蠹子代的数量明显下降。交叉接虫,波缝重齿小蠹子代的数量随接虫时间的延迟而降低。在林间用外激素引诱波缝重齿小蠹侵害黑山大小蠹的
Dendroctonus ponderosae and Ips pini endanger the same tree, the former predominantly harms the lower part of the tree trunk, whereas the latter mainly infects the upper trunk of the tree that has been harmed by the wood beetle. Investigation of the feathering holes on the surface of damaged tree bark showed that there was a significant negative correlation between the number of eclosion holes in the two bark beetles. Inoculation tests showed that the number of the two species of beehomoceros inoculated at the same time decreased obviously. Cross-docking insects, the wave number of severed teeth small borer offspring with the number of delayed pest and lower. Abdominal hormones in the woods were used to induce wave-stinkbug beetles against Montenegro beetles
